目的对某超市集中空调通风系统竣工验收卫生学评价,确保其卫生质量符合要求。方法采用风险评估法、检查表分析法和系统工程分析法进行评价。结果卫生检测结果显示送风中真菌总数和风管内表面积尘中真菌总数的最高检测值分别为950 cfu/m3和2 200 cfu/cm3检测结果超标,集中空调设备设施卫生状况存在一定的安全隐患。结论该超市的集中空调通风系统存在一定程度的污染,应加强管理。
Objective To evaluate the hygienic evaluation of the completion acceptance of the centralized air conditioning and ventilation system of a supermarket to ensure its hygienic quality meets the requirements. Methods The methods of risk assessment, checklist analysis and system engineering analysis were used for evaluation. Results The results of hygienic test showed that the highest detection value of the total number of fungi in the air supply and the dust on the inner surface of the air duct were 950 cfu / m3 and 2 200 cfu / cm3, respectively. The sanitary conditions of the centralized air-conditioning equipment and facilities have some hidden dangers. Conclusion The centralized air conditioning and ventilation system in the supermarket has some degree of pollution and should be strengthened.
